G type GJ type flexible rapier loom
The G1726 flexible rapier loom is a high-end rapier loom independently developed by Yuci Branch of Jingwei Fabric Machinery Co., Ltd. based on national conditions. Its main technical performance is at a relatively advanced level. The G1726J flexible rapier loom is a new type of rapier loom developed on the basis of the G1726 model with high speed, wide adaptability and low price. Suitable weaving varieties: This machine can weave cotton, wool, linen and other natural fiber fabrics, as well as viscose fiber, synthetic fiber fabrics and natural fiber and chemical fiber blended chemical fiber fabrics. This machine can weave light, medium, thick and heavy fabrics. Frame: This machine uses reinforced casting wall panels with a thickness of 80mm. The cross-section size of the main beam and round beam is large, and the stability of the frame is high. The height of the sword walking board from the ground is reduced to 943mm, and the center of gravity of the loom is lowered. The beat-up stroke is short and the beat-up force is strong, which can satisfy the weaving requirements even for particularly heavy fabrics. Shedding mechanism adopts Staübli2650 or GT405Ⅱ rotary electronic dobby. The heald frame has 20 large pages and is mounted downward on the left side. The weft insertion mechanism adopts conjugate cam transmission. When the effective weaving width changes, the adjustment is particularly simple. You only need to move the rapier head to the outside of the shed. It can reduce the invalid movement of the sword head. Due to the increase in vehicle speed, the leisure speed when clamping weft should be appropriately slowed down, and the speed will increase again when the rapier head enters the shed. Increase the size of the sword transfer wheel, and increase the enveloping angle between the sword belt and the sword transfer wheel to 180 degrees, extending the life of the sword belt. The sword head and sword belt are high-quality and miniaturized. The sword head and sword belt are guided by two rows of standard sword guide hooks or by a floating guide hook (GFG). The two forms are interchangeable. The beat-up mechanism adopts conjugate cam beat-up, optimized beat-up shaft bracket structure and beat-up shaft position, which reduces the deformation of each component of the beat-up mechanism during beat-up, has strong rigidity, reduces the beat-up stroke, and reduces the steel Friction of reed and warp. Warp let-off mechanism The let-off mechanism of the G1726 rapier loom adopts electronic let-off and consists of a fixed back beam and a movable back beam, the latter used to sense warp tension. The sensor continuously transmits the sensed warp tension signal to the control motor drive system. This signal is proportional to the actual warp tension. The motor speed is proportional to this signal, so that the warp tension is always stable. The parameters of the warp tension can be pre-adjusted. , it is required that the warp tension can be adjusted both during the weaving process and when the machine is stopped. The warp tension can be automatically compensated when the machine is stopped, and it can immediately return to the preset tension value when restarting. The let-off mechanism of G1726J loom is the same as that of G1724. Take-up mechanism: The G1726 rapier loom adopts electronic take-up. The weft density range is 5 to 200 picks/cm. For any change in weft density, the loom can display relevant weft density information through external pre-selected parameters. In order to adapt to the requirements of heavy fabrics, the diameters of the take-up roller and the press roller have been increased to increase the rigidity of the take-up. The G1726J loom adopts a mechanical coiling mechanism, and its lubrication is oil bath type. The electronic let-off and electronic take-up adopt synchronous electronic connectors to ensure that the loom has accurate weft density and set warp tension during operation, avoiding the possibility of driving marks to a large extent, thereby obtaining high-quality fabrics. Weft yarn supply method: Use a stand-alone electronic weft feeder to realize continuous unwinding of the weft yarn package. Weft yarn color selection device adopts electromagnetic color selection device controlled by PLC programmable controller, which can be matched with 8 colors. Automatic weft search mode: It has automatic weft search function and anti-weft stop function. The number of automatic reverse turns of the dobby or cam shedding mechanism can be set as needed. Weft breaking automatic stopping method adopts piezoelectric ceramic electronic sensing technology. Warp breakage automatic stop mode: Six rows of warp breakers, contact type warp breakage automatic stop. Fabric edge device adopts leno edge twisting device, and can also be equipped with fold-in edge, hot-melt edge or edge jacquard machine according to user needs. Starting braking device The electric motor drives the loom through electromagnetic clutch and brake. It has the characteristics of rapid starting and braking. Lubrication method: The cam boxes on both sides of the rapier and reed are spray lubricated and automatically circulated through the oil pump. The filter in the oil circuit keeps the lubricating oil clean, effectively extending the use time of the oil. The entire lubrication system The working condition is controlled by PLC, and multi-nozzle positioning spray is adopted to ensure full and effective lubrication. All other important mechanisms are separately packaged in the oil bath box, thus simplifying the maintenance of the loom and saving maintenance costs.
